Dave, being in Houston especially, tint those windows!!! It not only looks better but will drop your inner temps close to 20 degrees and prevent UV damage also.
I also concur on the limo tint. You cannot see out at night, and even in the daylight your vision is quite compromised.......
35% front, 20% rear. Ralphie recommended this to me and he was dead on.
